Problem: After upgrading to Spectrum 9.2.1 and/or hotfix patch H06 for 9.2.1, some users have experienced overall slowness in OneClick, and no performance dumps are being created for the SpectroSERVER.

Symptoms: Tomcat utilizing 100% CPU utilization, OneClick hanging, overall slowness, and intermittent connections to the OneClick console. The OneClick console connectivity is continuously bouncing between a connected state and disconnected state. Resulting in a red box around the OneClick Client.

Cause: Inefficiency with the Chassis Manager code in rendering the data in Spectrum OneClick.

Solution:

The workaround for this problem is to disable the Chassis Manager node by commenting out the Chassis Manager section in $SPECROOT/tomcat/webapps/spectrum/WEB-INF/topo/config/topo-app-config.xml file.

Make a backup of the $SPECROOT/tomcat/webapps/spectrum/WEB-INF/topo/config/topo-app-config.xml file.
